- Zest of 1 lemon
- 1/2 cup unsalted butter, melted

- 1 cup fresh or frozen blueberries
For the Streusel Topping:

Instructions:
1. Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners or grease it lightly.
2. In a large mixing bowl, whisk together the flour, granulated sugar, baking powder, baking soda, salt, and lemon zest.
3. In a separate bowl, combine the melted butter, eggs, buttermilk, and lemon juice. Mix until well combined.
4. Pour the wet ingredients into the dry ingredients and stir until just combined; be careful not to overmix. Gently fold in the blueberries.
5. Divide the batter evenly among the muffin cups, filling each about 2/3 full.
6. To make the streusel topping, combine the flour, brown sugar, softened butter, and cinnamon in a small bowl. Use a fork or your fingers to mix until crumbly.
7. Sprinkle the streusel topping evenly over the muffin batter in the cups.
8. Bake for 18-22 minutes, or until a toothpick inserted into the center comes out clean and the tops are lightly golden.
9. Allow the muffins to cool in the tin for a few minutes before transferring them to a wire rack to cool completely.
10. Enjoy warm or at room temperature, and indulge in the delightful combination of blueberry and lemon flavors in every delicious bite!
